What Is Magnesium Glycinate Good For? Benefits Guide
Discover what is Magnesium glycinate good for — from nervous system health and bone density to muscle cramps. Learn about key benefits and how Magnesium works.
What Is Magnesium Glycinate Good For?
If you've been wondering what is Magnesium glycinate good for, you're asking the right question. Magnesium is the fourth most abundant cation in the human body and a critical cofactor in hundreds of enzymatic reactions that regulate energy metabolism, neuromuscular function, cardiovascular health, bone integrity, and psychological well-being. It is naturally present in many foods, yet emerging evidence confirms that nearly two-thirds of the population in the Western world is not achieving the recommended daily allowance — a deficiency problem contributing to various health conditions.
Nature's Sunshine Magnesium provides nervous system support and assists in a wide variety of bodily functions. Used by several hundred enzymes in their daily tasks, Magnesium is found in the bones, soft tissues, and blood. It helps metabolize various nutrients such as vitamin C, Phosphorus, potassium, and sodium. Calcium and Magnesium are nutritional partners and work best when taken together.
This formula delivers 250 mg of Magnesium from Magnesium oxide and Magnesium amino acid chelate in a base of Licorice root, Kelp plant, Peppermint leaves, and White willow bark — bringing together mineral nutrition with time-honored botanical support. If you'd like guidance on whether this product fits your personal wellness goals, our naturopath is available for a free consultation.
Nervous System, Bones, and Muscles: Why Magnesium Matters
Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. It is required for energy production, oxidative phosphorylation, and glycolysis — making it truly indispensable for cellular energy generation across virtually all tissues.
Nervous System Health
Magnesium modulates neuronal excitability through voltage-gated Calcium antagonism and N-methyl-D-aspartate (NMDA) receptor blockade. Research suggests it plays a critical role as a natural NMDA receptor antagonist, modulating synaptic transmission and neuronal excitability. Deficiency is associated with increased risk of neurological symptoms, and supplementation supports normal nerve function.
Bone Density
Magnesium is involved in bone formation and influences the activities of osteoblasts and osteoclasts. It also affects the concentrations of both parathyroid hormone and the active form of vitamin D, which are major regulators of bone homeostasis. Observational data from large cohort studies found higher Magnesium intake associated with 2–3% greater bone density in women.
Muscle Cramps
Magnesium deficiency impairs muscle relaxation — muscles contract normally but may struggle to fully release when levels are low. It is the most studied mineral supplement for skeletal muscle cramps. While Cochrane reviews found it unlikely to provide meaningful cramp prophylaxis in older adults with idiopathic cramps (moderate-certainty evidence), evidence for pregnancy-associated leg cramps remains under investigation.
Early signs and symptoms of Magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. As deficiency worsens, numbness, tingling, muscle contractions and cramps, seizures, personality changes, abnormal heart rhythms, and coronary spasms can occur.

Who May Benefit from Magnesium Supplementation?
Understanding what is Magnesium glycinate good for starts with knowing who is most likely to need extra Magnesium support. The diets of most people in the United States provide less than the recommended amounts of Magnesium. It is estimated that between 56 and 68% of Americans do not obtain enough Magnesium in their diet on a daily basis to meet the recommended daily allowance.
Certain groups may be more likely to have Magnesium inadequacy, including:
- Older adults — as we age, Magnesium absorption and retention can decrease, leading to deficiency and health consequences
- Individuals with gastrointestinal concerns — conditions that affect absorption may reduce Magnesium uptake
- Those with type 2 diabetes — previous studies have demonstrated that diabetes is often accompanied by lower Magnesium status
- People on certain long-term medications — several drugs including diuretics and proton-pump inhibitors can cause Magnesium loss
- Active individuals — exercise may increase Magnesium requirements by 10–20%
Men older than 70 and teenage girls are most likely to have low intakes of Magnesium. If you're unsure whether this formula is right for you, our naturopath offers free consultations to help you evaluate your individual needs.
How to Take Nature's Sunshine Magnesium
Take 1 tablet daily with a meal. Each bottle contains 180 tablets.
Calcium and Magnesium are nutritional partners and work best when taken together. Vitamin D and Magnesium also help the body better absorb Calcium. In the absence of adequate vitamin D, Calcium absorption from both dietary sources and supplements is significantly diminished.

Preguntas frecuentes
What is Magnesium glycinate good for compared to Magnesium oxide?
Magnesium glycinate (bisglycinate) is often recommended for individuals with sensitive digestive systems, as it tends to cause fewer gastrointestinal side effects. The absorption of Magnesium chelated with amino acids, such as Magnesium glycinate, via the dipeptide transporter pathway has been observed. Magnesium oxide, by contrast, is the most concentrated form by weight but has lower bioavailability compared to organic salts. Nature's Sunshine Magnesium combines both Magnesium oxide and Magnesium amino acid chelate to provide 250 mg of Magnesium per tablet.
How much Magnesium do I need daily?
The Recommended Dietary Allowance (RDA) for Magnesium varies depending on age, sex, and life stage. The RDA for adult men is 400–420 mg/day, while for adult women it is 310–320 mg/day. During pregnancy, requirements increase to about 350–360 mg daily. Nature's Sunshine Magnesium provides 250 mg per tablet to help bridge the gap between dietary intake and recommended amounts.
Can Magnesium supplements cause side effects?
Magnesium supplements can cause nausea, cramps, and diarrhea in some people, with side effects more common at higher doses and with inorganic forms such as Magnesium oxide. Extra Magnesium from food is considered safe because the kidneys will eliminate excess amounts in urine. The Tolerable Upper Intake Level (UL) for supplemental Magnesium is 350 mg from supplements only — this does not include Magnesium found naturally in food and beverages.
Does Magnesium interact with any medications?
Yes. Magnesium can form insoluble complexes with tetracycline and quinolone antibiotics, reducing their absorption — these should be taken at least 2 hours before or 4–6 hours after Magnesium. It may also decrease the absorption of oral bisphosphonates (used for osteoporosis) and gabapentin. Loop and thiazide diuretics can deplete Magnesium, while proton pump inhibitors taken long-term may cause low Magnesium levels. Always consult a healthcare professional about potential interactions.
Why are Calcium and Magnesium often taken together?
Calcium and Magnesium are nutritional partners that work best when taken together. Magnesium is required for vitamin D activation, and vitamin D facilitates Calcium absorption in the intestine. Together, these nutrients support bone mineralization, muscle function, and electrolyte balance. This formula includes 40 mg of Calcium alongside 250 mg of Magnesium and 30 mg of Phosphorus — all key minerals for skeletal and muscular health.
Who is most at risk for Magnesium deficiency?
Certain groups are more likely to have Magnesium inadequacy, including older adults (due to decreased absorption), individuals with gastrointestinal disorders, those with type 2 diabetes, people with alcohol dependence, and individuals on certain long-term medications such as diuretics and proton pump inhibitors. It is estimated that between 56 and 68% of Americans do not obtain enough Magnesium daily to meet the recommended dietary allowance.
